This directly impacts on another bug which I'm in the process of 
investigating. On Solaris it was always possible to directly execute a 
JAR file as the kernel knows how to handle them, via jexec. When 32-bit 
support for Solaris was removed this broke as the 64-bit version of 
jexec was not being built. The fix is easy but it appears jexec is 
delivered into the $ARCH directory, and that location is hard-coded into 
the Solaris kernel, and is covered by a cross-product engineering 
contract. In the case of jexec that contract needs modifying, what I 
don't know is if there are any other similar cross-product dependencies 
that will be affected by this change.
